Prospects for the use of a combined distribution network for power supply of remote consumers.

The existing schemes of low-voltage distribution networks for agricultural purposes do not correspond to the modern technical standards. They deteriorate the reliability of power supply, the electricity quality, and increase its losses. The paper analyses the existing power supply schemes for private households and agricultural consumers in Russia and other countries. In North America, private houses are sometimes connected to the scheme using the 120-240 V individual transformers. A similar concept can be used to modernize the Russian electrical grid. The basic principle of the 0.95 kV electricity distribution system is to organize networks of this voltage class, with partial use of the main elements of the existing low voltage (0.4 kV) networks. The transformer substations for voltage 6/0.95/0.4 kV or 6/0.95 kV and individual low-power (0.95 (0.55)/0.4 (0.23) kV) transformers are installed in close proximity to the consumer. The new concept for the construction of the 0.95 kV electrical grid will reduce technical losses of electricity by 5-10% or more and commercial losses by 30% of the actual value.
